Pirate Kindred in Standard was already one good pirate away from being a viable deck. Now Thunder Junction has brought us not one - but three more incredible Pirates to push it into standard playability. The mana base is so smooth now that we have both Spirebluff Canal, and Cavern of Souls, but let's not forget the utility found in Mirrex, Otawara, Sokenzan, Plaza of Heroes, and Scene of the Crime that helps to add free spells to our list.
The 1-drops are solid with the new Reckless Lackey coming in hot early and providing cards/treasure late, Spyglass Siren as the already busted card that it is, Diamond Pick-Axe pumping up our threats while producing a steady stream of treasure, and 5 removal/tempo spells to clear away blockers and help us double-spell more easily.
The 2-drops are stellar with the new Malcolm having flying and haste while providing clues, the old Malcolm smoothing out our draws, the old Captain Storm pumping up the team, and Staunch Crewmate as the best Silvergill Adept ever printed to keep our hand stocked for double-spelling while finding all of our payoffs.
The 3-drops are even sweeter with the new Breeches copying our spells or providing burn for more interaction and reach, the old Breeches giving us incredible value/ramp/evasion, and Kitesail Larcenist as a catch-all answer for creatures/artifacts that also randomly ramps us by turning our stuff into treasures in a pinch - also everyone always forgets that ward costs are doubled by Roaming Throne.
Oh, did I mention that all of these awesome triggers are doubled by our only 4-drop, Roaming Throne? Add in the awesome sideboard with blue answers to control/midrange, red answers to aggro, and useful artifacts against combo that also fuel our maindeck synergies, and this list has serious legs to win any matchup. Izzet Pirates is going to be a wild ride and I am confident that it now has enough power to make it in Standard for years to come.
